The alternating current motor, the photoelectric encoder and the counting RS485 interface are disposed at the place of the main driving mechanism and the assistant driving mechanism.
Description
The utility model relates to a kind of sync control device, the sync control device of particularly a kind of variable roof bow formula structure belongs to building, mechanical control field.
Bow formula structure can be opened the variable roof system that roof system is a kind of large span, be widely used in round-the-clock sports ground, as the tennis court, ball park and football field etc., the open system on this bow formula structure roof adopts the mechanical synchronization mode, control method is open loop control, mechanical synchronization mechanism is a pinion and rack, two three phase alternating current motors drive the bracing frame on both sides, roof respectively, the both sides on roof are supported on respectively on two closed slides, because roof system is a heavy load, precision is not high in actual applications to utilize the mechanical synchronization mechanism of pinion and rack, in the motion process on roof, serious asynchrony phenomenon can occur, for example: certain of short duration pause can occur on one side, creep and beat, asynchronous error is greater than tens millimeters.These phenomenons have caused the large deformation on bow formula roof, have increased the wearing and tearing of rack-and-pinion lazy-tongs, have increased the noise of system, in the useful life of having reduced system, can cause danger to building and personnel when serious.
The purpose of this utility model is to overcome deficiency of the prior art, and the sync control device of a kind of variable roof bow formula structure is provided.
The technical solution of the utility model is as follows: adopted master-slave mode closed loop Principle of Synchronic Control, the left side controller on bow formula structure roof is as master controller, the right is a slave controller, constitute the master-slave mode synchronous control system, mainly comprise: the control room, user console, Programmable Logic Controller, variable frequency drives, cable, alternating current machine, the main driving machine structure, photoelectric encoder, counting-RS485 interface and from driving mechanism, user console, Programmable Logic Controller and variable frequency drives are arranged in the control room, link to each other between user console and the Programmable Logic Controller, carry out the transmitted in both directions of signal, Programmable Logic Controller links to each other with variable frequency drives, can send speed control signal, variable frequency drives links to each other with alternating current machine by long-distance cable, drive signal is sent to alternating current machine, end at alternating current machine is provided with photoelectric encoder, photoelectric encoder is sent to counting-PS485 interface with code signal, counting-RS485 interface links to each other with programmable controller, Programmable Logic Controller is main driving machine structure and from the movement velocity of driving mechanism relatively, movement velocity with the main driving machine structure is a benchmark, to carrying out speed governing from driving mechanism, the shaft extension end of alternating current machine links to each other alternating current machine with driving mechanism, photoelectric encoder and counting-RS485 interface is arranged on the main driving machine structure and from driving mechanism.
The utlity model has very strong practical value, solved the stationary problem of existing bow formula structure roof open system, have significant effect, as: the synchronized movement that has realized bow formula roof open system; Improved the noise of system's operation; The wearing and tearing of mechanical synchronizer and opener have been reduced; The fail safe and the reliability of system have been improved.
Below in conjunction with accompanying drawing the utility model is further described:
